'WINBOW-SAS-I LOCK.

Application filed September 25, 1.922, Serial No. 530,353. Renewed May 25, 1925.

T0 all iti/wm it may] cofiicmin.:

Be it knownv that 1, Gann A. S'rnorr, a citizen of the United States, and resident of Floral Park, in the county of Nassau and State of New York, have invented certain new and useful lniprcvements in l/Vindow- Sash Locks, of which the following is a full, clear, and exact specification.

This invention relates to window sash locks, and has for its object to provide simplified and impioved means for locking both the upper and lower sashes in different positions, so that they cannot be opened farther from the outside..

A special object of this invention is to provide for locking both saslies by a single catch having two loclnng tongues or meinbers zidapted to simultanecusly engage different locking means for securing both sashes in adjusted positions to a fined part of the window frame. Other objects will appear as the description proceeds.

The invention will be firsthereinafter described in connection with the accompany, ing drawings, which constitute part of this specification, and then more specifically defined in the claims at the end of the description. I

In the accompanying drawings, wherein similar reference characters are used to designate ccrresponding parts throughout the several views Figure 1 is a perspective view of portions of upper and lower window saslies and the beading separating them on the frame, one cf thelocliing devices constructed substantially in accordance withthis invention being attached to the meeting rail of the lower sash, and slotted strips to be engaged by said locking device or catch being shown attached to the dupper sash and the beading.

Figure 2 is a front elevation drawn to a larger scale of the saine parts, parts being in section.

Figure 3 is a longitudinal section vthrough the sashes showing the locking means in side elevation, as when looking from the right in Figures 1 and 2, and

Figure t is a detailed view of the catch in unlocked position. f

The upper and lower saslies of an ordinary window are indicated at 1. and 2, respectively. in Figures 1, 2 and 3, and the usual b for separating the grooves for es is jira'licated at 3. To the 'inner :farle er edge if Isquid beading' a strip et,

preferably of metal, is secured in any suitable manner, as by screws 5, said strip having` slots 6 formed at intervals along the same and the face of the beading below said slots being recessed, as at 7, Figure 2, The strip l is of a width to lie between the upper and lower sashes without interfering with the free movement thereof. Said strip preferably extends from a point adjacent the position of the meeting rails of the sashes when closed to a point far enough above the same to permit of several different adjustments of the lower sash.

An angle strip 8 is similarly fastened, as by screws 9, to the front face of the frame of the upper sash 1, and a series of slots 10 are formed in the forwardly projecting flange 11 of said angle strip. Said strip 8 may extend any desired distance along the vertical side member of the upper sash and have any desired number of slots 10 in its flange. rlhe strips l and 8 are thus arranged in close proximity to each other, with the flange 11 of the strip 8 occupying a plane slightly to the rear and at the right of the strip l as shown in Figures l and 2.

A double catch 12, having two locking tongues 18 and 19, is pivoted at 1d in a bracket 15 which is secured to the upper face of the meeting rail 16 of the lower sash 2 by screws 17. Said catch is preferably made of sheet metal of suitable shape to form the pivoted shanlr 18 and the two tongues or hooks 13 and 19, andthe sheet of metal is bent at 20 toA bring the upper end portion of the catch, which carries the upper Vtongue of hook 19 into the plane of the slots 10 in the flange 11 of the strip 8, while the lower portion of said catch, which carries the lower tongue or hook 18 is arranged in the plane of the slots 6 in the strip 4 attached to the beading 3. 1t will also be noted that the lower hoolr or tongue 13 is longer or extended farther to the left than the upper hook 19, so that said hoelrs are capable of simultaneously engaging slots in the strips 4l and 8, as best shown in Figures 1 and 2.

For actuating the catch a finger piece 21 may be bent forwardly at the edge thereof preferably about in the position shown, and to lock the catch in its strip engaging position a pawl 22 is provided, the same being pivoted at 23 to the bracket 15 and adapted to engage in a notch 24 in the edge of the catch, See Fig Said pIWl is als() i preferably formed with a forwardly bent niovenient because the' hook or tongue 19 tastens said sashes together, while the hook' or tongue 1&3 locksy bot-h to the linedl beading 3.

I claim I 1. A window sash lock having a catch pivoted to swing thereon, the tree end ot said catch having two integral locking members extending in the saine direction and offset laterally one from the other to simultaneously tasten both the lower and upper sashes of a window in adjusted positions.

2.' fr window catch to be pivotallyl attached to one window sash and havingv on itsy free end portion two integral locking members extending in the same direction for simultaneously 'tastening the! other sash thereto an-d both sashes to a ii'xture, the portion ot the catclrcarrying one otsaidlockingni'cnibers bei-ng oitsetlaterally from the portion carrying the other locking member lor the purpose specified.

E. A; sash loc i. comprising a bracket, a catch pivoted at one end to said bracket and having a locking hook on its lree end porlion anda notch in its rear edge` and a retaining pawl'pivoted on saidbracketin rear ol' said catch, and adapted to be swung to bring its lree end into engagement with said notch in the rear edge of the catch,- when the .latter is in locking position, tor holding saidv catch inthat position.

el; The combination with slotted strips to be secured lto one of a pair of window sashes and -to a part ol a window traine, respectively, ot a catch to be pivotally secured at one end to the other sash and'having two integral locking members on itsfree end portion for simultaneouslyA enga-ging said slotted strips tor fastening both sashes-in adjusted positions, one of said locking members being carried by the extreme free end portion of the catch and said extreme end portion and locking member carried thereby being offset laterally for the purpose specified.

5. The combination with slotted strips to be secured to one of a pair of sashes and to a partA ot a window frame, respectively, and arranged in parallel vertical planes, of a catch to be pivotally secured tothe other sash to swing in a vertical plane and having two `integral locking hook-shaped members extending in the saine direction and offset laterally one from the other on its tree end portiony for simultaneously, engaging said slotted; strips and'ta'stening'both sashes in adjusted positions'.l

6. The combination with slotted strips to be secured to: one ot a pair of sashesandA to a: partof a window frame, respectively, and arranged in parallel vert-ical planes, of a catch to be pivotally secured to theV other sash and-having two integral locking hook?, shaped members o1e different lengths lon its tree end portion and extending'in the same direction and roft'set laterally one from the other for simultaneously engaging said slotted strips and fastening both sashes in adjusted positions.

7. The combination with a slotted strip to be secured to the beading between the upper and lower sashesl of a window, of an angle strip to be securedto the upper sash and havin-g aforwardly extendingslotted flange arranged in aplaneparallel to that o't said slotted strip on the beading, and an integral double catch to be pivoted to the lower sash and ha ving-two integral hook-shaped lock-ing members extending` in the same direction and ol'set laterally one from the other to simultaneously engage both slotted strips.

8.A The combination with a slotted strip to be secured to the beading b'etweenthe upper andlower sashes of a window, of an angle strip to be secured to the upper sash and having a forwardly extending slotted flange arraiiged in a plane parallel to that of said slottet'l-strip on the beading, and anintegral double catch to be piroted to the lower slash to swing in a vertical plane and having' two integral hook-shaped locking members eX tending in-the saine direction and offset laterally one romthe other tovsimultaneously engage both slotted strips.

In testimony whereotl I have signed mv name to this specication.
